Just tried a little of my "eat now" one. Yeah, as he says, not going to win any baking competitions, but not unpleasant. Kind of halfway between a biscuit and a dense bread, with a bit of a dumpling thing going on from the suet. You can tell it's calorie rich, if I was hungry in the hills this would be very welcome.
Rough calorie estimate per biscuit:
Suet: 385
Oats: 180
Flour: 360
Dried fruit: 50
Total: 975 - so yeah, three a day sounds about right for somebody in the outdoors.
